1957 US $1 silver certificates are common among collectors. In circulated condition it has little added value - maybe 50 cents extra. A nice crisp uncirculated one may be worth $3 to $6 or more.
Blue Ink
All silver certificates dated 1928 to 1957 had blue seals and serial numbers. That color was used to distinguish the bills from other bills (Federal Reserve Notes, United States Notes) that were also issued. Today only green-seal Federal Reserve Notes are produced.
Serial Numbers
A bill's serial number is just a counter so including it in a question generally doesn't help to identify it or affect its value. There are collectors who will pay a premium for bills with low or patterned serial numbers; e.g.12345678 or 00000005.
Silver Value
It's no longer possible to redeem silver certificates for silver metal. That practice was ended after the price of silver was deregulated, to prevent people from "gaming" the exchange process by trading bills for metal and vice versa as rates fluctuated.
Silver Certificates were abolished by Congress on June 4, 1963 and all redemption in silver ceased on June 24, 1968. However the bills have never been withdrawn or demonetized so they're still valid legal tender at face value.
